The short version

  • Only Apache Druid has a free tier, so it costs nothing to try first.
  • Each has a real cost: Convex the Free and Starter tier includes only 1 million function calls and 0.5 GB of database storage per month before per-unit overage charges of $2.20 per million calls apply, as of August 2026.; Apache Druid open-source offering lacks high-availability, distributed architecture, and enterprise security features

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Convex

Apache Druid

  • Open-source offering lacks high-availability, distributed architecture, and enterprise security features
  • Requires native integration with Apache Kafka or Amazon Kinesis for real-time ingestion; custom integrations need development
  • High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment
